ABSTRACT:
Method and apparatus are disclosed for monitoring the quantity of single face paperboard on the bridge of a corrugator so that a unit length of paperboard will remain on the bridge for a preselected time irrespective of the speed of the corrugator to properly season the paperboard. Signals indicative of input and output of paperboard to the bridge are compared with a signal indicative of a preselected time and a signal is generated to effect changes in the single facer machine motor speed.
